If you are anywhere near this exhibition, at Weil am Rhein, Germany, and open until 16 March 2014, a visit seems essential. Taking a broad approach to light, art and design, the curators explain that the show aims to epxlore cutting edge art works and iconic designs while also enquiring about the future of light and sustainability, and the potential for further innovation. http://www.design-museum.de/en/exhibitions/detailseiten/lightopia.html

Thumbs up to the heroic inventor Alfredo Moser, who has developed a source of light that simply requires plastic bottles filled with water and a tiny bit of bleach. http://www.bbc.co.uk/news/magazine-23536914. Like the gravity lamp featured on this blog, this offers a very low cost lighting solution for the poor.

This simple yet and potentially massively useful innovation is under development, a device that generates light from gravity, providing a sustainable and affordable source of illumination: http://deciwatt.net/. Removing the need to rely on the fuel that countless people depend on, kerosene, with its deadly fumes and tendency to burn affecting millions each year, its environmentally damaging emissions and high cost, the gravity lamp could provide a safe, low cost alternative for billions of folk across the world

Thierry Cohen, a French photographer has produced a set of images which re-imagines iconic urban landscapes at night with no light pollutions. For a selection of his work please go to this feature in the New York Times. Thanks to Susan Seitinger for sending us this link.
